'Mii hv oh'vious that 1d iu thahivers @viennent and v him-iena .i i O My invention is of comparatively simple construction, can be produced at comparatively slight cost, the brake is light in weight, is strong, durable and efhcient and is exceedingly powerful owing to the fact that the brake surface has an extended area owing to the surfaces resented by the grooves and intermediate ri s. l

I claim: i

1. A brake `comprising a brake element, brake levers'pivotally connected together, brake shoes-:mounted in said brake levers, said brake shoes each having a bead and a 'contracted neck mounted in a keyway in the brake levers, whereby a radial and a lateral movement are automatically permitted to said brake shoes upon operation of the brake levers, and means for normally holding the ends of the brake shoes away from the brake element. I

2. A brake comprising a rotary element, grooves and intermediate ribs formed upon the periphery of said element, brake levers' pivotally connected together, brake shoes connected to said levers, said having grooves and intermediate ribs to lit the grooves and ribs of the rotary element, lateral. beads formed Lupon said brake shoes and a lateral keyway in each of said levers to receive said beads, and springs for holding said shoes at their ends away from said ro tary element, whereby said shoes are permit-- ted to have lateral lay to insure the Contact of the ribs on the s oes with the grooves on said element.

3, A brake comprising a rotary element provided with groovesand intermediate ribs upon its periphery, in combination with brakelevers provided with lateral keyways, and brake shoes provided with ribs and intermediate grooves, said shoes having beads mounted in the keyways to provide lateral movement of said shoes relatively toas'aid brake element.
